Ohio State University is telling students there’s an active shooter on campus and they should “Run Hide Fight.”

Ohio State’s official Twitter page retweeted a post from OSU Emergency Management saying there is an active shooter on campus in Columbus on Monday morning.

“Run, hide, fight” is standard protocol for active shooter situations. It means: Run, evacuate if possible; Hide, get silently out of view; or Fight, as a last resort, take action to disrupt or incapacitate the shooter if your life is in imminent danger.

A Columbus police dispatcher declined to comment on the reports, but police vehicles were seen at the scene.
